Can't dup NilClass on association methods

Question

I\'m using rails 2.3.5 and ruby 1.8.7. I\'m building a simple TODO manager. Where I have tasks that belong to a user and a user has many tasks.

I\'m using act

Got it.

From here,

Some of the classes inherited or included in your engine controllers may fail to get unloaded and cause trouble after the first request to your system.

For me, it was because I had a file in the lib that was monkey patching User model and the User model class in this file was not getting cached I suppose.

Calling unloadable in that class in the lib folder did the trick. So my lib file looks like this

class User < ActiveRecord::Base
  unloadable
  # stuff...
end

Thanks anyways.
